Detect thermal bridges after completion

@ Zaba12: I had that done by a company, the regional EV had such an offer. Purchase of such a device? I think there is something for the iPhone; but it would not have been effective for my purposes. @ Obstlerbaum: Of course, it could have been seen immediately after installation; but at that time I still trusted the "experts" and was not on site yet, and the GU (company XXX Massivhaus GmbH from Ilmxxxx in Thuringia) with its subcontractors exploited that and often quickly botched something together. That's why now the follow-up inspection; better after half a year than never... They have now been given a deadline for rectification, I am curious. This time I will be there and watch closely what is being done.

It's okay, I had the same experience with the first build. Good luck with the rework and don't skimp on your vacation days – frequent presence and interested inquiries noticeably improve quality.

I think there's something for the iPhone;

We have it. I have no comparison, but with it we could, for example, control our underfloor heating without any problems :)

What is the name of the app for the iPhone?

The camera is from Flir. Just google "flir iPhone".
